These sticky notes come in their own special case made of kraft paper, which helps keeps the sticky notes organized and prevents them from getting lost or scattered. The sticky notes are available in six colors, including red, yellow, green, blue, purple, black -- or other colors if you prefer. Each pad contains 20 strong sticky notes as well as 20 each of five different colored sticky flags. The case can be imprinted on the front or back with large imprint areas for both sides.
